MECHANICAL MOVEMENT.

Application filed June 15, 1925. Serial No. 37,170.

T all whom it may concern: v

Be it known that I, AAGE Rasmussen,

State of .lVisconsin, have invented certain new and useful Improvementsin Mechanical Movements; and I do hereby declare that the following is afull, clear, and exact description thereof. I

This invention relates to a mechanical movement, and is particularlydirected to a mechanical movement designed for cooperation with awinding mechanism.

Objects of this invention are toprovide a mechanical movement in whichrocking or reciprocatorymotion is changed into rotary motion in such amanner'that an impulse is transmitted to the rotary shaftirrespective ofthe direction of reciprocation of the operating member, and to provide asimple and effective type of mechanism for accomplishing this function.

Further objects are to provide a mechanical movement which occupies asmall amount of space, which will effect the winding of a. spring orsimilar member without requiring the use of a crank, which may becombined with a cabinet structure in a manner to economize space andavoid the outward projection of a crank, and which is of attractive andpleasing appearance, and does not mar the appearance of a cabinet towhich it is attached.

An embodiment of the invention is shown in the accompanying drawings, inwhich Figure 1 shows the device applied to a phonograph, such figurebeing a vertical elevation partly in section.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3 is a vertical sectional view on the line 33 of Figure 2.

Figure 41 is a sectional view showing a ratchet.

Figure 5 is a detail partly in section on the line 55 of Figure 3.

Referring to the drawings, particularly Figure 1, it will be seen thatthe device is shown as applied to the ordinary spring motor of aphonograph. The spring mechanism is indicated. at 1 and its windingshaft at 2. This winding shaft 2 carries a bevel gear 3 and a smallerbevel gear 4, both of which are rigidly secured to the shaft 2. A

transverse bearing plate 5 is supported by standardsfiand carries theouter end of the shaft 2.

A vertical shaft? extends upwardly in front of the shaft 2, as shownmost clearly in Figures 1, 3 and 5. ilhisvertical shaft is carried in anupper and alower bearing 8 and 9, respectively. ,A bevel gear 10 isrigidly secured to the shaft 7 and a small hexagonal member ,11 is alsorigidly secured to such shaft adjacent its upper end, and is providedwith a flange 12. This hexagonalinember receives a ratchet wheel 13which is apertured-to.conform to the hexagonal contour of the member 11,as most clearly indicated in Figure 2.

The ratchet wheel .13 isprovided with an outwardly projecting; portion lupon which the ratchet teeth are formed andis provided with a pair ofnwardly positioned shoulders which form projecting hubs 15. {Theseprojecting hubs pivotally reeeiveithe apertured portion of a pairofstrap members or plates 16 and 17 as most clearlyshownin Figure 8, oneofthe members,foriinstance, 17 continuing, outwardly to form an operat;ing arm or lever 18. Thearn 18-is,there fore, carried by means of'thehubs of the ratchet wheel 13 and is free to oscillate about such hubs. Asmall pawl 19 is carried between the members 16 and 17 and is urgedinwardly by means of a spring clamped between such members, as shown inFigures 3 and 4, such spring being indicated by the reference character20. Obviously, it is usually desirable to provide a slight channel orgroove in the members 16 and 1'? to receive the outwardly projecting endof this spring.

A bevel gear 21 is freely mounted upon the shaft 7 and is provided witha downwardly extending spacing sleeve 22 which rests upon the discportion of the bevel gear 10, as shown in Figure 3, and consequentlycorrectly positions the gear 21, such gear meshing with the bevel gear3. This gear 21 is further provided with a shouldered hub 23 whichcarries a ratchet wheel 24 simi lar to the ratchet wheel 13. A similarpair of arms are provided which engage the hub of the ratchet wheel 2%,one of such 1 H arms projecting outwardly, as indicated at 25.

A spring pressed pawl 26, similar to the pawl 19 is provided andcooperates with the ratchet wheel 24.

It is to be noted that the ratchet wheels 13 and 24 have their teethoppositely turned, and the pawls 19 and 26 are correspondinglypositioned. The arms 18 and project outwardly and are bolted together bymeans of a threaded rod 27, a spacer being positioned between the arms18 and 25. This pin or arm 27 projects upwardly through a slot 28 formedin the top 29 of the cabinet such, for instance, as the cabinet of aphonograph. If desired,- a plate 30 may be secured to the upper side ofthe phonograph and may be provided with a correspondingly arcuate slot31 through which the pin 27 projects. A handle 32 is rigidly secured tothe upper end of the pin above the plate 30.

The operation of the apparatus is as follows :-lVhen it is desired towind the mechanism, the operator grasps the handle 32 and rocks it backand forth in the arcuate slot 31. Motion is transmitted first to thegear 10 and then to the gear 21 in a reverse direction, such gearsrotating the corresponding gears 4 and 3, and consequently rotating theshaft 2 at each reciprocation. Thus the mechanism may be very quicklyand easily wound up and does not require an outwardly projecting crankwhich detracts from the appearance of the machine and also is verylikely to damage due to its exposed position.

It is to be understood that the handle 32 is completely housed by theordinary cover of the phonograph.

It will be seen that a very simple type of mechanical movement has beenprovided in which reciprocatory or rocking motion is Although theinvention has been described in considerable detail, it is to beunderstood that the invention may be variously embodied and is,therefore, to be limited only as claimed.

I claim:

A mechanical movement comprising a base member and a top member havingsockets rigidly carried thereby, a vertical shaft extending between saidsockets, a bevel gear rigidly secured to said shaft adjacent its lowerend, a second bevel gear spaced therefrom and having an integraldownwardly extending sleeve resting upon said first mentioned bevel gearto hold said bevel gears in spaced relation, a pair of rocking levers,pawl mechanisms operating in opposite directions and joining said leverswith said shaft and with said last mentioned bevel gear, a frame workhaving vertical side members extending upwardly from said base andhaving a transverse member, a horizontal shaft having an end journaledin said transverse member, and a pair of bevel gears carried by saidhorizontal shaft and meshing with said first mentioned bevel gears.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of Wisconsin.
